CSP

Corrugated Steel Pipe (CSP) Culverts for Drainage and Stormwater Management

Corrugated Steel Pipe (CSP) offers the ideal combination of strength, durability, and flexibility, making it a top-performing solution for a wide range of infrastructure applications. Commonly used in culverts, storm sewers, and stormwater detention and retention systems, CSP is a cost-effective and versatile product that meets the needs of both rural and urban drainage projects.

Why Choose Corrugated Steel Pipe?

CSP is engineered for longevity and structural performance. Its corrugated profile increases the load-bearing capacity of the pipe, making it capable of withstanding high soil and traffic loads. It is particularly well-suited for:

  • Culverts under roadways, railways, and driveways
  • Stormwater drainage systems
  • Municipal and industrial storm sewer infrastructure
  • Underground stormwater detention/retention systems

Coating Options to Match Service Life Requirements

We supply CSP in various protective coatings to meet your specific design and environmental conditions:

  • Galvanized Steel – Offers excellent corrosion resistance and an economical service life of 25 to 50 years, depending on site conditions.
  • Aluminized Type 2 – Provides enhanced durability and corrosion resistance in acidic or aggressive soil environments, extending service life to 75+ years.
  • Polymer-Laminated CSP – Delivers premium corrosion and abrasion protection, ideal for highly aggressive environments requiring a design life of 100+ years.
